在两个页面之间互相写其控件内的值

定义A页面,定义TextBox id="TextBox1"和Button id="Button1"
后台代码:

private   void  Page_Load( object  sender, System.EventArgs e)
         {
             this .Button1.Attributes.Add( " onclick " , " window.open('SelectData.aspx?rec=TextBox1','newwin','toolbar=no,menubar=no,status=no,location=no,resizable=no,scrollbars=no,width=218,height=185,top=190,left=300');return false; " );
        }

定义界面B:  TextBox id="TextBox1"和Button id="Button1" 和type="hidden" id="name"
脚本:

< SCRIPT language = " JavaScript " >
             var  parwindow;
            parwindow = self.opener;
             var  recv  =  document.all( " name " ).value;
             if  (parwindow  !=   null ) 
             {
            document.all( " TextBox1 " ).value = parwindow.document.all(recv).value;
            }
            
             function  changetext() 
             {
                 if  (parwindow  !=   null ) 
                 {
                     try {
                            parwindow.document.all(recv).value  =  document.all( " TextBox1 " ).value;
                        }
                     catch (e)
                         {
                        }
                 }
            }
         </ SCRIPT >

 

放在form后
后台代码:

private   void  Page_Load( object  sender, System.EventArgs e)
         {
            name.Value  =  Request.QueryString[ 0 ];
             this .Button1.Attributes.Add( " onclick " , " changetext();window.close() " );
        }
